Function core.time.MonoTimeImpl.currTime
The current time of the system's monotonic clock. This has no relation to the wall clock time, as the wall clock time can be adjusted (e.g. by NTP), whereas the monotonic clock always moves forward. The source of the monotonic time is system-specific.
On Windows, QueryPerformanceCounter
is used. On Mac OS X,
mach_absolute_time
is used, while on other POSIX systems,
clock_gettime
is used.
Warning: On some systems, the monotonic clock may stop counting when the computer goes to sleep or hibernates. So, the monotonic clock may indicate less time than has actually passed if that occurs. This is known to happen on Mac OS X. It has not been tested whether it occurs on either Windows or Linux.
